A vehicle body rear portion includes a vehicle body floor and a fuel tank. The vehicle body floor has a tire storage area that is hollowed downward. The fuel tank is supported by a lower surface of the vehicle body floor on a forward side of the tire storage area. A stiffener is attached to the vehicle body floor at a forward position of the tire storage area. The stiffener extends along a vehicle body forward/rearward direction and reinforces an upper region of the fuel tank of the vehicle body floor.

A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.

A motor vehicle has at least one pressure vessel for storing storage medium, preferably fuel, at least one pressure relief device for pressure relief of the at least one pressure vessel, and at least one opening through which storage medium flows out during a pressure relief.

A cross member structure of a vehicle body includes a floor panel (2) provided below a vehicle interior in the vehicle body (10); side sills (3) that are provided on both sides of the floor panel (2) in a vehicle width direction and extend in a front-rear direction of the vehicle body (10); a cross member (4) that extends in the vehicle width direction and connects the side sills (3) to each other; and a reinforcement (5) that is provided between the cross member (4) and the floor panel (2) and extends in the vehicle width direction, wherein the cross member (4) includes a curved portion (41) that is curved to at least one side in a vertical direction of the vehicle body (10) outward from the reinforcement (5) in the vehicle width direction.

A vehicle includes a vehicle body having a frame structure provided with a pair of right and left side rails, and hydrogen tanks and a secondary battery disposed in a region between the side rails. The side rails have deformed portions that are deformed due to a vehicle front collision load at the time of a vehicle front collision, and the hydrogen tanks are disposed in front of the secondary battery or on both outer sides of the secondary battery in a vehicle width direction such that the deformed portions, when the amount of movement of each of the deformed portions of the side rails has reached a predetermined amount, reach the hydrogen tanks without reaching the secondary battery.

A cross member structure of a vehicle body includes a floor panel (2) provided below a vehicle interior in the vehicle body (10); side sills (3) that are provided on both sides of the floor panel (2) in a vehicle width direction and extend in a front-rear direction of the vehicle body (10); a cross member (4) that extends in the vehicle width direction and connects the side sills (3) to each other; and a reinforcement (5) that is provided between the cross member (4) and the floor panel (2) and extends in the vehicle width direction, wherein the cross member (4) includes a curved portion (41) that is curved to at least one side in a vertical direction of the vehicle body (10) outward from the reinforcement (5) in the vehicle width direction.

This disclosure relates to an assembly that cools a traction battery of a vehicle, in particular a hybrid electric vehicle. The assembly can include at least one fuel tank, and at least one traction battery that is arranged outside the fuel tank and is thermally connected to the fuel tank. The assembly can further include at least one fuel pump that is arranged in the fuel tank and at least one fuel line that is connected and/or can be connected to a pressure side of the fuel pump. A connection portion of the fuel tank is thermally connected to the traction battery. Fuel can be used to cool the connection portion, which cools the traction battery.

A structure for a lower portion of a vehicle body includes a right side sill (14), a right floor frame (17), a right cross member (68), and a muffler. A fuel tank is provided on an inner side of the right floor frame (17) in a vehicle width direction. The right cross member (68) spans between the right floor frame (17) and the right side sill (14) and extends in the vehicle width direction. Furthermore, the muffler is provided in a region enclosed by the right side sill (14), the right floor frame (17), and the right cross member (68). The right cross member (68) has an upward deformation guiding part (77). The upward deformation guiding part (77) is formed to be able to be deformed upward due to an impact load (F2) input to the right side sill (14).

Typical composite panels are brittle and unable to support transverse pressure loads that might be imposed on the panels. For example, the use of typical panels around fuel tanks of a vehicle are unable to support transverse pressure loads that might be imposed on the fuel tanks during a crash of the vehicle or a ballistic impact to the fuel tanks. In the embodiments described herein, panels include face sheets that are bonded to a foam core. The foam core includes a corrugated core sheet that is formed from a highly ductile material, such as Polyethylene or Aluminum. When a transverse pressure load is imposed on the panel, core crush of the foam occurs as the core sheet elongates from its original corrugated shape to a curve shape during deformation. This allows the panel to dissipate the energy of the transverse pressure load applied to the panel.
